Sounds like a job for the Struts Wiki!

often, so the list below has been compiled from this mailing list archive and other published
articles to consolidate the arguments for using tiles.  If you have experience with tiles,
please add, modify, or subtract from this list with the goal of creating a list that people
can use when evaluating whether to use tiles or not on their project.

common page elements? tiles definitions support inheritence. If you have 60 jsps, you have
@include header.jsp repeated in every jsp. Next, imagine a new requirement dictates that the
menu should be moved from the right side to the left. You now have to change 60 jsps.  If
your application uses tiles, you change only one jsp, all of your jsps inherit from this layout

tiles does what you want to do very cleanly, integrates with Struts very nicely, and is a
standard solution that you don't have to develop or document, and that your team members may
already have experience with or at least be more excited about learning than an in-house,
one-off system since that experience will have more value in the marketplace.

places. If the developers follow mvc properly, a new person new to the project can get a sense
of site flow and structure by looking at only struts-config.xml and tiles-defs.xml

useful for creating a tile such as Amazon's "books you've recently browsed". The tile can
plug in to any page without considering the Struts action code for that URL.
